Pseudolymphomatous folliculitis (PLF), which clinically mimicks cutaneous lymphoma, is a rare manifestation of cutaneous pseudolymphoma and cutaneous lymphoid hyperplasia. Here, we report on a 45-year-old Japanese woman with PLF. Dermoscopy findings revealed prominent arborizing vessels with small perifollicular and follicular yellowish spots and follicular red dots. A biopsy specimen also revealed dense lymphocytes, especially CD1a+ cells, infiltrated around the hair follicles. Without any additional treatment, the patient's nodule rapidly decreased. The presented case suggests that typical dermoscopy findings could be a possible supportive tool for the diagnosis of PLF.
假性淋巴瘤性毛囊炎（PLF）临床症状类似皮肤淋巴瘤，是皮肤假性淋巴瘤和皮肤淋巴样增生的一种罕见表现。在此，我们报告一例患有PLF的45岁日本女性。皮肤镜检查结果显示有明显的树枝状血管，伴有毛囊周围和毛囊小的淡黄色斑点以及毛囊红点。活检标本还显示密集的淋巴细胞，尤其是CD1a+细胞，浸润于毛囊周围。未经任何额外治疗，患者的结节迅速缩小。该病例提示典型的皮肤镜检查结果可能是诊断PLF的一种辅助手段。
